Expert Solution
Step 1
The Algorithm of the code:-
1) Take input from the user as a string.
2) Split the string into individual words and store it in the norm variable.
3) Convert each word to lowercase and store it in a different variable named low.
4) Create an empty dictionary named freq.
5) Iterate through each word in the low variable and check if it is already present in the freq dictionary.
6) If it is present, increment its value by 1 else add it to the dictionary with the value 1.
7) Iterate through each word in the norm variable and print the word and its corresponding value from the freq dictionary.
